Reaction Conditions:

with dibutyltin dilaurate;4-methoxy-phenolReflux;

Steps:

2 Comparative Example 2 Ethylene glycol diacrylate
A mixture of the following components was charged to a copper wire mesh packed with a temperature monitor / temperature controller, a magnetic stirrer, a dry air inlet, a 29 cm diameter copper column packed with a distillation head, a distillate ratio-removed vapor pressure thermostat and Progressive distillate(0.05 mol) of ethylene glycol, 25.83 g (0.3 mol) of methyl acrylate (MA), 100 ml of a four-0.03 g (0.0002 mol) of p-hydroxyanisole and 0.11 g (0.0002 mol) of dibutyltin dilaurate.The mixture is then raisedWarm to reflux. In the course of the reaction into a certain amount of air, under constant pressure in the continuous heating reflux, while removing the reaction azeotropic mixtureMA-Methanol. After the reaction reached the end point, the reaction solution was cooled to 50 ° C, 0.10 g of neutral activated charcoal was added and the stirring was continued for 0.5-1The reaction solution was decompressed under reduced pressure and the filtrate was distilled under reduced pressure to give 5.35 g of ethylene glycol diacrylate in a yield of76.9%, purity 54.8%.
